In addition to Dave Biddle's excellent comments, from a systems perspective, since we're all embedded and supported by natural systems, let's look at how they operate.
Consider where incinerative processes work, where they don't work, how often they happen, and what type of fuels they use. It might prove a good guide to see if, where, and how to incorporate incineration into human processes, and keep a healthy integration with our communities and world.
Any ecological biologists or biomicrists, fire away.

Apologies that the GreenYes list has been hijacked by this conversation, but I'll just share one last thought which is that plasma is clearly incineration when the resulting gases are incinerated. This is why the European Union considers plasma, gasification and pyrolysis to be incinerators -- combustion of waste, even if it's treated first, is incineration:<image.tiff>
The European Union Parliament's Directive on Incineration of Waste:
"'[I]ncineration plant' means any stationary or mobile technical unit andequipment dedicated to the thermal treatment of wastes with or withoutrecovery of the combustion heat generated. This includes the incineration byoxidation of waste as well as other thermal treatment processes such aspyrolysis, gasification or plasma processes in so far as the substancesresulting from the treatment are subsequently incinerated."
Not to mention the question of spending over $400 million to destroy valuable resources that could be recycled and composted. I suggest we put our money and efforts into stopping the twin problems of resource depletion and waste creation, rather than subsidizing wasting by finding new ways to juggle mixed discards.
I'm happy to continue this discussion with anyone off list to not overwhelm the entire email list.

Subject: [GreenYes] Re: Biosolids. Sealed means independent testing !
Sealed means independent testing with the seal of the testing lab embossed on the pages like a notary.
I will send you a copy off net of sampled sealed test info and the details onmachine I observed which was greatly improved since 2004.
The energy balance varies depending on what is put in as is demonstrated in the Westinghouse system. Plama reduic of Coal yield is much better than sewer sludge.
Plasma loves all plastics especially auto fluff.
Fla has lots of waste streams that are more or less pure high hydrocarbon containing feedstock types this allows even greater efficiency and thruput.
By the way anyone that says Plasma is incineration is clueless on the process. NO FLAME inert gas no oxygen involved. And really really clean. EPA emissions sheet on Medical Waste will be sent to you off net.
AS far as cost is concerned the deal that the old plasma company made to my county was FREE system contracted waste stream and agreed on price of electrical power which was better than our existing Covanta contract. Lake Co has one of three legacy waste to enegy plants in Fla. Uses Natural Gas to keep the temps consistent and lots of water to control emissions. We also have a class Blandfill and ash to contend with. And Lake CO also recycles glass, plastic, cardboard and metals cans and white goods.
